I just bought a 79 Cutlass Supreme with a 260v8. Car is in good condition two doors good paint and all, when you start it up it starts and idles good. Now here is where I need help, when you give it gas when its in park you start hearing a knocking sound, I though it was a rod ready to go, but when you get out to hear it the knocking is comming from right under the 2bbl carb. And you can only hear the knocking when you give it gas? Talked to a couple of so called mechanics one says its a rod about to go, and the other one says its a bad lifter? Any help please
